Use the XML Serializer Task to read an XML document that conforms to a user-specified schema (or DTD) and output an XML document consisting of a single root node that contains the entire input XML document as a string. (This task is essentially the inverse of the XML Parser Task that accepts a single node containing XML and breaks it out into a mappable XML document.)
At runtime the task accepts an XML document that conforms to the input schema (the user-specified schema) and serializes the input XML document into a string. It then outputs an XML document with a root element whose data is the string as constructed above.
